When you're the Foo Fighters, you do whatever you want on stage. At the Firefly Festival on Friday night, Dave Grohl decided that they were a different band and would have some fun for a bit.
He told the crowd, "We're gonna do something we've never done before. For the next 20 minutes, we're a bar band called the Holy Sh**s that plays classic rock songs."
And they did, and it was good.
"Under Pressure" by Queen!
"Ain't Talkin' 'Bout Love" by Van Halen!
"Miss You" by The Rolling Stones!
Because they're the Foo Fighters, that's why.
